Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already provide comprehensive behavioral information: readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true. The description adds minimal value beyond this - it confirms the HTTP method is GET (which aligns with readOnlyHint) but doesn't provide any additional behavioral context about what specifically gets retrieved, potential side effects, authentication requirements, or rate limits. With good annotation coverage, the description meets the lower bar but doesn't add meaningful behavioral insight.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
